The B&W diamond series speakers lover clean power, a lot of it (closer to the max recommended wattage is better) and bi-wiring at least.
I wouldn't use anything less than 250 watts with it. More would be better as the speaker also dips in impedance to around 3 ohms at certain points during playback which can clip or cause distortion from the amp.
But if most your listening is 2 channel, I would recommend getting the HTM2D which is less demanding and will still match up well with your 802D mains.
I have 803D mains and then sound much, much better with the new Spectron MK2 I bought than the previous Rotel RB-1090 (380 watts/channel) I had. I know the Rotel vs. the Spectron isn't a fair match-up even if the power was the same but these speakers love good clean power.
I would presume the HTM1D is rated for 500 watts like the 802D mains and unless you plan on doing a lot of HT listening and buy an appropriate amp for it, I'd suggest buying the HTM1D (which I have and is rated for 300 watts). It is a terrific center channel.
